I have a simple question
Thread Content
Under such operating conditions, the pressure vessel category shouldn’t be Category II, right?
The composition of the medium is not very clear. For the first group of media, the operating pressure is 0.12 MPa (G), the design pressure is 0.55 MPa (G), and the volume is 125.2 m3; based on these values, classifying it as Category II makes sense
The first group of media does not have Category I.
Which type of container does the original poster think it should belong to?
Thank you, I didn’t understand the first set of media. The first group of media is extremely hazardous due to its flammability and explosiveness, but why is it labeled as moderately hazardous? I’m a complete novice in this area – please don’t laugh at me: lol
When classifying, it’s necessary to follow the more stringent requirements; having more comprehensive markers for moderate hazard levels is beneficial for the design. For example, major regulatory standards specify requirements for the materials used in bolt gaskets when dealing with highly penetrative, moderately hazardous media
We need to see what medium it is; there are specific requirements
